摘要
为探求指针式喷灌对广西甘蔗的影响,选择在南宁市宾阳县廖平农场高效节水工程开展大田试验,试验设置指针式喷灌3个处理和无灌溉(CK)1个对比。试验结果表明:采用指针式喷灌能提高糖料蔗的单产,有灌溉设施的蔗区单量6.37 t/亩,比无灌溉蔗区4.02 t/亩多2.35 t/亩;有灌溉设施的蔗区平均含糖分为14.04%,比无灌溉的蔗区14.29%低0.25%。
In order to study the influence of pointer sprinkler irrigation on sugarcane of Guangxi, field experiment was conducted at Liaoping Farm in Binyang County of Nanning City. Three groups of sprinkler irrigation tests and one group of no irrigation test were conducted for comparison. The results of test demonstrate that pointer sprinkler irrigation can increase the yield of sugarcane with a yield of 6.37t/mu, 2.35t/mu more than that of no irrigation farm with a yield of 4.02t/mu （1 hectare = 15mu）. The average sugar content of sugarcane out of irrigated farms is 14.04%, 0.25% lower than that out of farm without irrigation with a average content of 14.29%.
